How to measure Electrical Conductivity of Aluminium alloys

Zappitec's model 12Z allows quick and precise measurement. Here is the procedure:

Quality Control of Copper Bus Bars

1. Temperature Equalization

Place your standards in contact with the part you want to measure to allow their temperature to enter equilibrium. This takes a few minutes but it only needs to be done once. If the parts to measure are small, place everything on top of a thick copper or aluminium plate, just to make sure the temperature will be the same. The bottom part of Zappitec Conductivity Standards is exposed to allow for quick temperature equalization.

2. Turn on the instrument

Turning On Zappitec model 12Z Conductivity Meter

Turn on the instrument by pressing the left button.

3. Calibrate the instrument on the apropriate standard

Calibrating model 12Z Conductivity Meter

Select the standard which has a conductivity closest to the material to be measured.
Example: if measuring high conductivity aluminium use the standard with ~59 %IACS.
Place the probe on the standard and press the center button. A message will appear on the display indicating that the standard was recognized and the unit is now calibrated.

4. Electrical Conductivity measurement on Aluminium parts

Measuring conductivity of aluminium with ZAPPITEC 12Z
Place the probe on the part you intended to measure and read the value on display. It's that simple! The result is alread temperature-compensated for 20°C, which is how the conductivity of materials are compared. A single point calibration using the correct standard minimizes the errors even if the temperature is not 20°C.
